Neonatal Period
First 6mo
6-12mo
13-24mo
2-3yrs
3-7yrs
Prenatal Period - Correct Answer Responds first to tactile stimuli
Reflex Development
Innate tactile, proprioceptive, and vestibular input reactions
Neonatal Period - Correct Answer Tactile, proprioceptive, and vestibular inputs are critical from
birth onward for the eventual development of body scheme.
Vestibular system, although fully developed at birth, continues to be refined and impacts on the
infant's arousal. Helps the infant to feel more organized and content.
Visual system develops as infant responds to human faces and items of high contrast places
approximately 10in from the face.
Auditory system is immature at birth and develops as the infant orients to voices and other
sounds.
First 6mo - Correct Answer Vestibular, proprioceptive, and visual systems become more
integrated and lay the foundation for postural control, which facilitates a steady visual field.
Tactile and proprioceptive systems continue to be refined, laying the foundation for
development of somatosensory skills.
Visual and tactile systems become more integrated as the child reaches out and grasps objects,
laying the foundation for eye-hand coordination.
,Infant movement patterns progress from reflexive to voluntary and goal directed.
6-12mo - Correct Answer Vestibular, visual, and somatosensory responses increase in quantity
and quality as the infant becomes more mobile.
Tactile and proprioceptive perception becomes more refined, allowing for development of fine
motor and motor planning skills.
Tactile and proprioceptive responses also lead to midline skills and eventual crossing of midline.
Auditory, tactle, and proprioceptive perception is heightened allowing for development of
sounds for the purpose of communication.
Tactile, proprioceptive, gustatory, and olfactory perception are integrated, allowing for primitive
self-feeding.
13-24mo - Correct Answer Tactile perception becomes more precise allowing for
discrimination and localization to further refinement of fine motor skills.
Further integration of all systems promotes the complexity of motor planning as the toddler's
repertoire of movement patterns expands.
Symbolic gesturing and vocalization promotes ideation, indicating the toddler's ability to
conceptualize.
Motor planning abilities contribute to self-concept as the toddler begins to master the
environment.
2-3yrs - Correct Answer This is a period of refinement as the vestibular, proprioceptive, and
visual systems further develop, leading to improved balance and postural control.
Further development of tactile discrimination and localization lead to improved fine motor
skills.
Motor planning and praxis ideation also progresses during this period for more skillful
occupational performance.
3-7yrs - Correct Answer Child is driven to challenge sensorimotor competencies through
roughhouse play, playground activities, games, sports, music, dancing , arts and crafts,
, household chores, and school tasks. These occupations provide opportunities to promote
psychosocial development and self-esteem.
Crossing Midline - Correct Answer As the child becomes more mobile, movement against
gravity and weightshift increase, leading to eventual crossing of the midline, often in attempt to
reach for a toy, while weightbearing on the opposing upper extremity for balance. Begins at 9-
12mo.
Laterality - Correct Answer Hemispheric specialization for specific tasks varies with different
individuals
Bilateral Integration - Correct Answer As the child experiments with movement, the nervous
system is stimulated, and the resulting sensations help the child to coordinate the two sides of
the body. Begins at 9-12mo.
Visual-Motor Integration - Correct Answer Dependent upon the lower level skills of visual
attention, visual memory, visual discrimination, kinesthesia, position in space, figure ground,
form constancy, and spatial relations.
Oral-Motor Control - Correct Answer Developed in the area of feeding, provides the
foundation for early oral communication and later language development.
Rooting Reflex - Correct Answer Onset Age: 28wk gestation
Integration Age: 3mo
Stimulus: Stroke corner of the mouth, upper lip, and lower lip.
Response: Movement of the tongue, mouth, and/or head toward stimulus.
Relevance: Allows searching for and locating feeding source.
Suck-Swallow Reflex - Correct Answer Onset Age: 28wk gestation
